#include <userver/storages/redis/transaction.hpp>
Atomic sequence of commands (https://redis.io/topics/transactions). Please note that Redis transaction implements isolation, but not all-or-nothing semantics (IOW a subcommand may fail, but the following subcommands will succeed). Methods will add commands to the Transaction
object. For each added command a future-like object will be returned. You can get the result of each transaction's subcommand by calling Get()
method for these objects. Commands will be sent to a server after calling Exec()
that returns RequestExec
object. You should not call Get()
method in a future-like subcommand's object before calling Get()
method on RequestExec
object.

Finish current atomic sequence of commands and send it to a server. Returns 'future-like' request object. The data will not be set for the future-like objects for subcommands if Get()
method of the returned object is not called or redis did not return an array with command responses. In the last case Get()
will throw a corresponding exception.
